The Affinity Diagram process follows brainstorming. After brainstorming the sticky notes are in no particular order. The team needs to sort them into categories.
- Team members silently begin to read and then arrange the sticky notes into categories (similar care processes, themes or pathways). You will generally have between 2 and 6 categories.

- Re-read all the sticky notes and remove any double ups.
